Guthix's Blessing is an entity summoned to aid the player when using the ability of the same name. It will heal the player who called it for 8% of their maximum life points every 2 seconds, over a period of 10 seconds for a combined healing of 40% of maximum life points. It can be attacked and killed by any player (in certain PvP situations) or monster, causing the healing effect to end.

Players can only attack and kill the butterfly at the Duel Arena, the Wilderness, or the Clan Wars. The butterfly cannot be attacked or killed in over-world Duelling, trying to do so will produce the following message:

When using a multi-target ability like Chain the player will receive a message in the game filter stating that You cannot fight other people's followers here., preventing the player from killing their own butterfly.

Although the examine text claims it is Guthix's ghost, gods do not have ghosts or spirits that linger after death, as they explode into energy when they die.
